dc.description.abstractIndia is a major exporter of Basmati rice in the international market due to exemplary quality traits. Attempts were made to characterize the aromatic rices which possess a wide array of diversity which can be incorporated in Basmati improvement programmes. A set of 36 aromatic accessions was evaluated for various morphological and quality traits during Kharif 2017. Significant genotypic variations was observed for days to 50% flowering, plant height, ear bearing tillers/m2, number of grains per panicle, lodging, grain yield, milled rice recovery, head rice recovery, grain length, grain breadth, length/breadth ratio and kernel length after cooking. The genotypes Laldhan, Hung-mi-hriang-matsan, UPR 35565-10-1-1, IET 22187 (RP 4594-121-148-24-11) and Basmati 867 were early in maturity. The genotypes, IR 841- 85-1-1-2 was early maturing, semi-dwarf, and high yielding along with good tillering ability and high number of grains per panicle. Another genotype, IET 22187 (RP 4594-121-148-24- 11) was early maturing and high yielding along with high grain length and good kernel length after cooking. Two genotypes, Bony Cay and Kalikhasa showed resistance to bacterial blight against pathotype PbXo-7. These genotypes can be used in Basmati improvement programmes for various traits. With an aim of combining the elongation ratio of Pusa Basmati 1509 with long slender grain type of Basmati 370, a large F2 population derived from a cross of Pusa Basmati 1509 and Basmati 370 was subjected to quality analysis. Considerable variation was observed for all the progenies. Among these, 53 progenies were identified which possessed desirable grain length suitable for raw milling. Two progenies, 18091 and 18678 also possessed good KLAC and thus can be used to select best segregants in the near future.en_US
